Trifazni napetostni priključek za silikonske gumijaste grelnike

The star connection method of the three-phase voltage of the silicone rubber heater is to connect the lower end of each phase power supply or load to the lower point, and the other lower end is the lead wire, which is the three-phase line of the three-phase voltage. Silicone rubber heating plate heating element: The nickel alloy heating wire is wound around the glass fiber wire, and the heating power can reach 2 . 1W/c㎡, ogrevanje pa je bolj enakomerno . vlaga, ki so odporni na vlago, in silikonske gumijaste materiale, ki so odporni na kemikalije nickel-chromium alloy wire and insulating material. It has a high design power density, fast heating, high thermal efficiency and long service life. In addition to being used for heating and heat preservation of general constant power belts, it can also be used in places that need heating in some cases. PI heating film uses improved PI film, which has better Toplotna prevodnost in jo je mogoče prilagoditi v skladu z zahtevami za oblikovanje . Lahko izpolnjuje različne zahteve po ogrevalni moči in zahteve o ogrevalni temperaturi na različnih območjih in uresničitev temperaturne porazdelitve na ogrevalni površini . Za ožičenje zvezd lahko nevtralno točko (imenovano nevtralna točka), ki jo lahko tudi nevtralno linijo tvorijo tri-fazni sistem {22} {22}, ki jih je mogoče oblikovati tri-faza s sistemom štirih Wire {22. Trifazni trižični sistem . Seveda, ne glede na to, ali obstaja nevtralna črta ali ne, lahko zemeljska žica trifaznega petžičnega sistema ali trifaznega štirižičnega sistema dodate ločeno.

The three-phase voltage triangle connection method of the silicone rubber heater is to connect the power supply or load of each phase end to end in sequence, and lead out each connection point as the three-phase line of the three-phase voltage. The triangle connection has no neutral point and cannot lead out the neutral line, so there is only a three-phase three-wire system. After adding the ground wire, it postane trifazni štirižični sistem .

For the three-phase AC voltage of the star connection method, the line voltage is times the phase voltage, and the line current can be equal to the phase current. When the load of the three-phase system is balanced, even if the neutral line is not connected, no current will flow through it for a long time. When the three-phase load capacity is unbalanced, the neutral line should be connected, otherwise the load of each phase bo imel neenakomerno delitev napetosti .

Pri trifazni napetosti metode povezave trikotnika je napetost linije enaka fazni napetosti, linijski tok
